This invention relates -to condensers and more particularly to constructions for supporting the various component parts of t assembly. This application is a continuation in art of my 00- endin application, Serial 0. 393,436 filed eptem er 18th,1929. One of the objects of the invention is to relieve the turbine of the weight of the water boxes. Another object is to provide flexibility between the condenser casing and the j permit .relative movement of the water boxes and the condenser shell. Other objects and advantages of the invention will be in art obvious and in part pointed out hereina er.

In the drawings in which similar reference arts Figure 1 is a side elevatibn oi a condenser constructed in accordance with the practice of the invention and its supporting means, portions of the condenser being broken away to show the internal construction,

Figure 5 is an enlarged view of a water tube showing its connections to the tube sheets when the invention is applied as i Fi re 4.

n the drawings the condenser is shown comprising a. shell A housing a lurality of circulating water tubes B exten 'ng len hwiseof thecasing A and suitably seale at their ends in tube sheets C and D, and C and D. In Figure 1 the ends of the tubes are expanded in tube sheets C and D but in Figures 4 and 5 the tubes are expanded in tube sheet D and 'packedin tube sheet 0. In the former construction expansion of the 1980. Serial No. 488,320.

tubes is permitted by the yieldable nature of the water box supports hereinafer more specificall described, which ield to the extenslon o the tubes. In the atter structure expension of the tubes is permitted by the packlng at one end thereof.

11 Figures 1 and 3 tube sheet 0 is suitably attached to an inlet water box E having inlet openings F and G adapted to be connected to a suitable source of circulating water (not shown). Likewise a discharge water box H is attached to the tubesheet l) and is provided with discharge openings J and K for connection to suitable pipes, not shown, to carry away the circulating water. In Fi re 4 the tube sheets G and D are attache the water boxes so that no part of the weight of the tube sheets or of the water tubes is supported by the water box supports.

The casing A is provided with a steam inlet flange L which is adapted to be rigidly connected to a turbine exhaust hood 0. Remote from the steam inlet flange L with respect to the path of the steam through the condenser shell A there is provided an outlet 1 through which condensate -may be withdrawn.

v Intermediate of the length of the tubes B are support sheets 1 tightly fitted in the condenser shell A through which the tubes B are passed and by WhlCh they are su ported in their intermediate portions. In Figure 1, by this construction, themajor portion of the weight of the water tubes is supported by the condenser shell and consequently upon the turbine outlet 0. In the form of the invention illustrated in Figure 4 the entire weight of the tubes and tube sheets is supported upon the turbine outlet'O.

Because of the tight fit of the tube support sheets 1 within the casing A it is necessary to make provision for the removal of condensate from the compartments created by said support sheets. For this purpose inverted siphons m are provided which connect the end compartments to the center compartment from which the condensate outlet leads. Uncondensible gas and air are withto the end of the shell A' instead of to A, being connected thereto drawn from the casing by suitable means, not shown.

In accordance with this invention the condenser shell A is arranged to be supported inde endently of the water boxes E and H. To t is end the casing A is rigidly attached to the steam turbine exhaust hood or conduit 0 at the flange L. The water boxes E and H are free to move with res ect to the casing y means of con.- nections R and S preferably of some flexible material such as rubber.

In Figure 1 the' connection R is interposed between an end flange T of the casing A and the tube sheet 0 and ma be bolted thereto or attached in any suita 1e manner. Similarly the connection S as is shown in detail in Figure 3. is interposed between an end flange U of the shell A and the tube sheet D.

2 The connection S is reinforced on the inside by means of rings W having outwardly extending flanges. Similar rings X having upturned flanges conforming to theU-shape of the connection reinforce it on the outside.

The flange U of the casing A is attached to a connection S by bolts Y passing through the flange U, the rmgs W and X and the connection S to make a tight joint. Similar bolts Z pass through water box H, the tube sheet D, rin s 'W and X and the connection S also to ma joint. The connection R is similarly attached to the flange T of the casing A and the water box E and tube sheet C.

In Figure 4.- the flexible connections R and S are similarl made, the difference being that the tube slieets C and D come between the flexible connections R and S v and the flanges T and U of the casing A instead of between the flexible connections and the 4 posts endo which flanges of the respective water boxes.

Referring particularl toFigure2the water boxes E and H are each supported on separate frameworks each comprising upright suitably anchored to a base 9 by bolts banc ored into the the base 9 and 'assing through foot pieces 7' attached to t e base the posts 7. At their upper ends the posts 7 are provided with angles it upon are bolted short sections of I-beams p by means of outwardly extendin brackets g which may be formed integral y with the water boxes. Diagonal bracing for the posts 7 is provided in the form .of angles a and t attached at the center by a gusset plate. Each tubes B within the condenser" support thus provided for the water boxes E and H is independent of the other and permits movement of the water boxes with re spect to each other upon ex ansion of the ue to a change of temperature. s

In a condenser 20 feet long the maximum tube expansion between temperatures of 32 and 212 would hardly equal one-half inch and in ordinary practice expansion of more the water box flange d of the e a tight pension adoFted in Figure 4 that flexible mounting o the water boxes in that particular construction will not be necessary the expansion of the tubes will efiect upon the position of the water boxes.

The construction above described provides support for the casing A entirely independent of the water boxes E and H. The steam inlet opening attheflange L may be designed to provide an area of opening whiohat the vacuum within the shell A provides an upward force suflicient to carry the entire weight of the condenser shell A together with all of the weight of the tube support sheets and all or a major portion of the weight of not have anythe tubes, and also, in the construction shown 7 1n Fi re 4, the weight of the tube sheets 0 an D. g

It has been found in the past that the upward force produced by the vacuum due to the size of the steam inlet openings into the condenser tends to lift the condenser from its supports, whereby the greater part of the weight is carried by the turbine instead of by the condenser supports. With the construction above described the casing and its contents are suspended from the turbine while proper base 9.
